Description
The current ISA/CPU feature detection on the SPARC architecture is either broken or at best insufficient and does not support even a fraction of the features provided by the newer Core S3 and S4 implementations.

Here, we should assume at least Solaris 11.1 (JDK9).

ILW = CPU feature detection is broken, Solaris/SPARC only, no workaround = MMH = P3

As a first step, introduce support for Core S3 and S4 features.
